The case developed after Kohlhepp was arrested on charges of kidnapping an Anderson woman last November. Spartanburg County deputies say Kohlhepp confessed to killing the workers at the Superbike Motorsports shop in 2003.

Kohlhepp is also charged with killing Charles David Carver, the kidnapped woman's boyfriend and Johnny and Meagan Coxie, a husband and wife who disappeared in 2015.
